If the voltage remains constant and resistance increases, what happens to current?

Explanation:
With a constant voltage, current follows I = V/R. If you raise the resistance while keeping V the same, the quotient V/R gets smaller, so the current decreases. For example, doubling the resistance halves the current. The current wouldn’t increase or stay the same under these conditions, and it wouldn’t become negative unless the voltage polarity reversed. So the current decreases.
